Title: Eprom with shutter
Inventor: MATSUNO TOSHIAKI
IPC: H01L21/8247
Filed: 1989-09-04
Abstract: PURPOSE:To maintain data written in an IC chip or to make possible the erase of the data without adhering a light-shielding covering film on the opening part of an IC package by a method wherein an EPROM is provided with a freely openable and closable shutter, by which the opening part sisshut and the irradiation of ultraviolet rays on the IC chip is intercepted. CONSTITUTION:Data is written in an IC chip mounted in an IC package 1 and thereafter, a shutter 3 is shut and an opening part 2 is blocked. Whereupon, ultraviolet rays are not irradiated on the IC chip 4 and the data programmed in the chip 4 is maintained. On the other hand, in case the programmed data is erased and another data is inputted, a projecting piece 3a of the shutter is pushed to open the shutter 3 and ultraviolet rays are led in through the opening part 2. The chip 4 is irradiated with these led-in ultraviolet rays and the programmed data are all erased. Thereby, even if a light-shielding covering film is not adhered, the irradiation of ultraviolet rays is intercepted by simply shutting the shutter 3, data programmed in the chip 4 is protected and when the shutter 3 is opened, the data is easily erased.

Title: Processing circuit for runaway and limit-testing device
Inventor: KOMATSU DANICHI
IPC: G06F1/04
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To surely attain an interrupt processing, even at the time of a hardware runaway by decreasing the clock signal frequencies to be supplied to a microcomputer before an interrupt acceptance processing is operated for frequencies which are capable of the normal operation of the microcomputer by an interrupt request signal. SOLUTION: An interrupt request signal generated due to the underflow of a watch dog timer 1 is supplied to not only an interruption control circuit 2 but also to switch circuits 4 and 5 so that the circuits 4 and 5 can be controlled. The circuit 4 is closed at normal times, and when the interrupt request signal of the timer 1 is supplied, the circuit 4 is turned into an opened state, and a switch circuit 5 is opened at normal times. When the interrupt request signal of the timer 1 is supplied, the switch circuit 5 is switched to a closed state. Thus, when the interrupt request signal is outputted from the timer 1, a clock signal to be supplied to the inside part of the microcomputer is switched from a first clock signal ϕ2 which is a frequency f1 to a second clock signal ϕ4 which is a frequency f2.  The microcomputer can be operated even at a low voltage side by decreasing the frequencies as much as possible, so that at least the timer 1 processing can be operated normally even at a time of runaway.
